The monthly shindig is called the “Moonlight Jamboree,” and it’s rapidly becoming a must-be-there night out for musicians and fans of the local roots music scene.

On Saturday, “Moonlight Jamboree” will definitely be rockin’ the house. Eric Erkinnen will launch the evening’s festivities with a solo set at 7:30pm, followed by the Charlie Watts Riots stripping down their high-energy rock to an unplugged format. The honky-tonkin’ Tern Rounders will wrap up the night with a closing set of their own, featuring selections from their fine debut CD, “A Different Land.”
